I-Firefox Community Forum

Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

King regards, Anton Siemonsma

Hi,

Dunno if this is by design, but a lot of installers don't play well when installed from standard user account with elevated privieleges. Firefox installer on Windows 10, when ran from GUI or admin PowerShell, accesses AppData fodler under standard user account that started the elevated process. Thus, it's not possible to install it if admin account doesn't have access to user folder, as on my system it doesn't for security reasons.

It's a minor inconvenience to need to explicitly log into admin account and do it there. But as this is a disease among installers I'd rather have them play well with normal security.

You may disagree here, and I understand if you do. Just pointing it out.

I've been having this annoying popup about XULRunner encountering an error. From what I've read, XULRunner is a legacy integration with Firefox. Sure enough, I see Mozilla Firefox installed. But un-installing it doesn't help. Soon, it is re-installed, and the error comes back. I have a feeling that some application is using XULRunner and Firefox as a component, but I don't know what it could be. Is there any way to find out, and stop that application from installing Firefox and XULRunner? Or at least getting its problem fixed?

'since the update from Aug 20 to 129.02 cannot open lobstr.co on firefox (after 8 captchas get error). Have no problem opening lobstr on Windows or Google. So this has to do with your last update. What do you suggest?

why and or how can i update Firefox. i am running Firefox 126. every time i open the browser the auto update opens and fails to download. i tried loading it through Safari, also failed. anyone have a clear and simple solution? the forum seems to have a lot of complicated work a rounds. any help would be appreciated

We use Firefox Developer Edition in our Enterprise and any auto-update (whether it be the background process or 'check for updates' button) fails to work, due to much of mozilla.org being blocked by our internet security. I want to be able to provide our security team with a definitive URL that the auto-update process uses.

I found mentions of aus5.mozilla.org but in testing this has proved not to be used.

How do I stop these recurring update notices? Every 3 seconds. I'll update when I am ready as this current one does not affect me at all. For a while I fell for it, stopped what I was doing and did the ridiculous update, it still continues! I can move on to a different non-Mozilla browser if I have too. Return the option to not update and/or do it manually. FF127.0.2

Hello, I just got a new macbook air because fluid was spilled on the previous one. The older laptop works but the display is not functioning. So I can't use the migration assistant, which requires responding to screen prompts, which in this case are not visible to me. I also just updated my password. Is there a way to recover this data?
